Re: [Xen-devel] consistent LVM snapshot of domUs from dom0



Hi Mike, well, I maybe don't understand where the question is ;) but I guess that Your procedure is perfectly correct (for creation of a checkpoint of running system), if You want to restore the backup later, You restore system into running state, so a filesystem is in state consistent with running system....

Hi Mike,
I think that this problem can be solved using procedure Mark proposed -
freeze filesystems of all running domUs using some xm command, then
create snapshot and unfreeze them all again. I think that You won't need
suspend at all.
We just now need to implement it :)


Just a question about unsafely. I have implemented iscsi and zfs as
combination with Xen on Linux. Is the only safe procedure:

pause
memory snapsnot
[send out disk snapshot]
resume
